☆ Dyson spheres: Could alien megastructures exist in the Milky Way? Scientists found 7 places to look

Now, a new study that looked at 5 million stars in the Milky Way galaxy suggests that seven candidates could potentially be hosting Dyson spheres — a finding that’s attracting scrutiny and alternate theories. If Dyson spheres really exist, what could they be used for? “Freeman Dyson said that we should dismantle Jupiter — the whole planet (for the raw materials).”That supercolossal scale probably means that Dyson spheres, if they exist at all, are very rare. “However, contamination by circumstellar debris disks, which mimic Dyson Sphere infrared signatures, remains a concern,” he added in an email. However, he added, the radiation fingerprint of the seven Dyson sphere candidates might be explained by natural phenomena as well.

☆ UK Nobel Prize-winning physicist Peter Higgs dies aged 94

London —Physicist Peter Higgs, whose theory of an undetected particle in the universe changed science and was vindicated by a Nobel prize-winning discovery half a century later, has died aged 94, the University of Edinburgh said on Tuesday. Higgs described himself as “incompetent” in the physics laboratory at school and at first preferred maths and chemistry. What came to be known as the Higgs boson would solve the riddle of where several fundamental particles get their mass from: by interacting with the invisible “Higgs field” that pervades space. That interaction, known as the “Brout-Englert-Higgs” mechanism, won Higgs and Belgium’s Francois Englert the Nobel prize in physics in 2013. CERN’s massive Large Hadron Collider finally proved to be the sledgehammer needed to crack the nut, and in 2012 two experiments there independently found the Higgs boson.

☆ Scientists are building tunnels under South Dakota for a $3 billion experiment that could solve some of the universe's grandest mysteries

Estimated to cost at least $3 billion, the project DUNE (Deep Underground Neutrino Experiment), is led by scientists at the US Department of Energy's Fermilab. AdvertisementCavern excavation at the Sanford Underground Research Facility in South Dakota began in 2017. The beam will then travel underground for 800 miles to the detectors at the South Dakota Sanford Underground Research Facility. The Sanford Underground Research Facility is located at a former gold mine.

☆ How antimatter engines could fly humans to other stars in just a few years

AdvertisementInterstellar travel is only something humanity has achieved in science fiction — like Star Trek's USS Enterprise, which used antimatter engines to travel across star systems. "Annihilation of antimatter and matter converts mass directly into energy," Weed, cofounder and CEO of Positron Dynamics, a company working to develop an antimatter propulsion system, told Business Insider. Space travel at record speedProxima's star system, shown here, could be reached in just five years with antimatter-powered technology. For example, let's take a trip to our nearest star system, Proxima, about 4.2 light years away. And since the '80s, there's been talk of thermal antimatter engines, which would use antimatter to heat liquid, gas, or plasma to provide thrust.

☆ A weirdly wobbly 'muon' particle might revolutionize physics by revealing a 5th force of nature or another dimension
▼ + stars: | 2023-08-15 | by ( Sonam Sheth | Jessica Orwig | ) www.businessinsider.com time to read: +5 min

A subatomic particle called the muon is wobbling far more than leading physics models can explain. Its unusual behavior could be evidence of a fifth force of nature or a new dimension. And the reason could be evidence of a new, fifth force of nature. But there are still cosmic wonders we don't understand — mysteries that the discovery of a fifth force of nature may help solve. One possible explanation is that the muons' behavior is dictated by a fifth force of nature.

☆ The odd behavior of a subatomic particle may shake up physics

Read moreWASHINGTON, Aug 10 (Reuters) - The peculiar wobble of a subatomic particle called a muon in a U.S. laboratory experiment is making scientists increasingly suspect they are missing something in their understanding of physics - perhaps some unknown particle or force. The experiment studied the wobble of muons as they traveled through a magnetic field. Casey was alluding to a principle called Lorentz invariance that holds that the laws of physics are the same everywhere. The researchers shot beams of muons into a donut-shaped superconducting magnetic storage ring measuring 50 feet (15 meters) in diameter.

☆ Physicists Move One Step Closer to a Theoretical Showdown

On July 24, a large team of researchers convened in Liverpool to unveil a single number related to the behavior of the muon, a subatomic particle that might open a portal to a new physics of our universe. All eyes were on a computer screen as someone typed in a secret code to release the results. The first number that popped out was met with exasperation: a lot of concerning gasps, oh-my-God’s and what-did-we-do-wrong’s. The new measurement matched exactly what the physicists had computed two years prior — now with twice the precision. “It really all comes down to that single number,” said Hannah Binney, a physicist at the Massachusetts Institute of Technology’s Lincoln Laboratory who worked on the muon measurement as a graduate student.

☆ Scientists build 'baby' wormhole as sci-fi moves closer to fact
▼ + stars: | 2022-11-30 | by ( Will Dunham | ) www.reuters.com time to read: +3 min

Scientists have long pursued a deeper understanding of wormholes and now appear to be making progress. It was a "baby wormhole," according to Caltech physicist Maria Spiropulu, a co-author of the research published in the journal Nature. But scientists are a long way from being able to send people or other living beings through such a portal, she said. The researchers observed the wormhole dynamics on a quantum device at Alphabet's Google (GOOGL.O) called the Sycamore quantum processor. A wormhole - a rupture in space and time - is considered a bridge between two remote regions in the universe.
